Who was the first emperor of the Western Han Dynasty?

The Western Han Dynasty (206 -9 BC) is an ancient dynasty in China, which is called the Han Dynasty together with the Eastern Han Dynasty. In the first 206 years, Liu Bang was enfeoffed as Hanwang by the overlord of the Western Chu Dynasty. Then, after four years of Chu-Han War, Liu Bang finally unified the world in the first 202 years, claiming the title of emperor and making Chang 'an its capital. History is called the Western Han Dynasty.

Xiang Yu named Liu Bang as the "Forty-one County of Bashu Hanzhong" and Hanzhong as the "Hanwang" under his rule. When he became emperor, he named the country the name of the dynasty. Chang 'an, the capital of Liu Bang, is located in the west of Luoyang, the capital of Han Dynasty established by Liu Xiu. For the sake of distinction, it was called "Western Han Dynasty" in history, and sometimes it was called "Xijing" according to the relative position between the capital and the Han Dynasty built by Liu Xiu. The Han Dynasty established by Liu Bang preceded the Han Dynasty established by Liu Xiu, so it was also called "pre-Han Dynasty" in history.

? Liu Bang (256 BC-65438 BC+65438 BC +0. 095 June), Emperor Gaozu of Han Dynasty, was born in Pei Jun Fengyi, Han nationality. Born in the civilian class, Qin was then the curator of Sishui Pavilion, and set off for Yu Pei (now Peixian County, Jiangsu Province), known as Peigong in history. After Qin died, he was named Hanwang. Later, he defeated Xiang Yu, the overlord of the western Chu Dynasty, in the Chu-Han War and became the founding emperor of the Han Dynasty (Western Han Dynasty). The name of the temple was changed from Emperor Gaozu to Emperor Taizu. Since Sima Qian in the period of Emperor Wu of the Han Dynasty, it has been called Gaozu and posthumous title as Gaudi, so it is called Emperor Gaozu, Taizu or Gaudi in history. He made a decisive contribution to the unification of Han nationality, China and the protection and development of Chinese culture.
